The key difference between chlorophyll A and B is that the chlorophyll A is the primary photosynthetic pigment in plants and algae while the chlorophyll B is an accessory pigment that collects energy and passes to chlorophyll A. Chlorophyll is a family of natural pigments that are present in plants and algae and is responsible […]
Difference Between Decomposer and Detritivore
The key difference between decomposer and detritivore is that the decomposer is a saprophytic organism which decomposes and recycles dead organic matter in the environment while detritivore is a type of decomposer which consumes decaying organic matter and digests within its body in order to break down and obtain nutrients. An ecosystem consists of all the […]
Difference Between Stem and Trunk
The key difference between stem and trunk is that the stem usually refers to the main structural axis of a plant while trunk usually refers to the main structural axis of a tree. Stem and trunk are two botanical names sometimes used in a similar sense. Strictly speaking, there is some difference between stem and […]
Difference Between Fermentation and Respiration
The key difference between fermentation and respiration is that the fermentation occurs in the absence of oxygen while the respiration needs oxygen. Organisms require energy to perform cellular activities. Hence, they generate energy molecules in the form of ATP. They use different substrates and break down into different forms, and the releasing energy converts into […]
Difference Between Allele and Locus
The key difference between allele and locus is that the allele refers to one of the two or more alternative sequences of a gene at a certain locus while the locus refers to a certain location on a chromosome where a gene can be found. In the form of genes, genetic information inherits from parents […]
Difference Between Embryo and Fetus
The key difference between embryo and fetus is that the embryo is the term that describes the development of a young offspring in mothers’ womb from the day of fertilization to end of the eighth week of gestation while the fetus is the term that describes embryo from the eighth week onwards until the offspring […]
Difference Between Cellulose and Starch
The key difference between cellulose and starch is that the cellulose is a structural polysaccharide that has beta 1,4 linkages between glucose monomers while the starch is a storage polysaccharide that has alpha 1,4 linkages between glucose monomers. Starch and Cellulose are macromolecules belonging to the same group of carbohydrates. Carbohydrates are one of the […]
Difference Between Active Transport and Passive Transport
The key difference between active transport and passive transport is that the active transport moves molecules from low concentration to high concentration against the concentration gradient via a semi-permeable membrane while passive transport moves molecules along the concentration gradient from high concentration to low concentration. Furthermore, Active transport requires energy for molecular movements in contrast […]
Difference Between Chromosome and Chromatid
The key difference between chromosome and chromatid is that a chromosome is a long thread-like form of a DNA molecule while a chromatid is one-half of two identical copies of a replicated chromosome. In fact, two chromatids are joined together by a centromere to form a chromosome. Chromosome and chromatid are closely related structures that […]
Difference Between Oestrogen and Progesterone
The key difference between oestrogen and progesterone is that the oestrogen is the main female sex hormone, which is responsible for the growth of the female reproductive system and secondary sex characteristics while the progesterone is another female sex hormone, which is important for the maintaining and sustaining a pregnancy. Women synthesize several sex hormones including […]
